# Roblox with AMD Ryzen 7 9700F + NVIDIA GeForce RTX 3070

The combination of an AMD Ryzen 7 9700F and NVIDIA GeForce RTX 3070 delivers exceptionally high frame rates in Roblox, with the 1080p Ultra preset still achieving 270 FPS average and the 4K Ultra preset maintaining a playable 102 FPS average. The measured data shows this system ranks 1266th out of 3010 tested combinations for this game, placing it in the upper portion of the database while revealing that Roblox's modest rendering demands are met with substantial headroom across all tested resolutions and settings.

Resolution Scaling

The FPS degradation from 1080p to 4K follows a consistent pattern across all four settings presets, though the absolute drops vary significantly depending on the graphics load. At Low settings, the average FPS falls from 413 at 1920x1080 to 156 at 3840x2160, representing a 62% reduction in frame rate. This steep decline indicates that even at Low settings, the pixel throughput demand at 4K begins to strain the GPU, though the final 156 FPS figure remains far above typical display refresh rates.

The Medium preset shows a similar relative drop, from 376 FPS at 1080p to 142 FPS at 4K, a 62% decrease. The High preset demonstrates the same pattern with values falling from 332 FPS to 125 FPS, again a 62% reduction. Ultra settings produce the largest absolute decline, moving from 270 FPS at 1080p down to 102 FPS at 4K — a 62% drop that mirrors the other presets almost exactly. This uniform scaling across settings strongly suggests that resolution is the dominant factor in performance degradation, with the GPU becoming progressively more limiting as pixel count increases.

Interestingly, the scaling between 1080p and 1440p is much gentler. At Low settings, the drop from 413 to 276 FPS represents a 33% reduction, while at Ultra the fall from 270 to 180 FPS is a 33% decrease as well. The transition from 1440p to 4K is where the curve steepens dramatically, with Low settings dropping from 276 to 156 FPS (a 43% reduction) and Ultra falling from 180 to 102 FPS (a 43% reduction). This pattern indicates that the RTX 3070's 8 GB GDDR6 memory and 256-bit bus are sufficient for 1440p but face significantly higher pressure at 4K, where the additional pixel fill rate demand becomes the primary bottleneck.

GPU Role

The NVIDIA GeForce RTX 3070, built on the Ampere architecture with a GA104 chip, provides the rendering foundation for this combination. Its 5888 shading units, 184 texture mapping units, and 96 raster output pipelines deliver the raw throughput needed to sustain the high frame rates observed. The boost clock of 1725 MHz, combined with a base clock of 1500 MHz, keeps the GPU operating at high frequencies during Roblox sessions, contributing to the consistent performance across all measured configurations.

The 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth, which proves adequate for Roblox's texture and geometry demands even at 4K resolution. The 14 Gbps effective memory speed ensures that data transfer does not become a limiting factor, as evidenced by the 4K Medium preset still achieving 142 FPS average with a minimum of 121 FPS and maximum of 163 FPS. The GPU's 20.31 TFLOPS of FP32 compute performance and 317.4 GTexel/s texture rate are more than sufficient for a sandbox title with Roblox's visual complexity.

The RTX 3070's 46 ray tracing cores and 184 tensor cores are largely idle in this workload, as Roblox does not heavily utilize these specialized units. The GPU's 165.6 GPixel/s pixel rate becomes the more relevant specification at higher resolutions, and the data shows this is where the card begins to show its limits. At 4K Ultra, the 102 FPS average indicates that pixel throughput is nearing its ceiling, though the result remains playable. The 61st percentile ranking among all GPUs and an average benchmark score of 17208 place this card in the mainstream-to-performance tier, which aligns with its measured behavior in Roblox where it delivers high but not unlimited frame rates at 4K.

CPU Role

The AMD Ryzen 7 9700F, with 8 cores and 16 threads based on the Zen 5 Granite Ridge architecture, provides ample processing headroom for Roblox's simulation and physics workloads. The CPU's boost clock of 5.50 GHz and base clock of 3.80 GHz, combined with a 32 MB shared L3 cache, ensure that game logic and entity updates are processed without becoming a bottleneck. The 4 nm TSMC process node and 8,315 million transistors enable efficient operation, with a 65 W TDP that keeps thermal demands modest.

The PassMark single-thread score of 4691 indicates strong per-core performance, which is critical for Roblox's often single-threaded game logic. The multi-thread score of 36470 and integer math score of 120788 demonstrate the CPU's capability to handle concurrent tasks, though the data suggests that at 1080p Low settings, the 413 FPS average is likely approaching the engine's frame pacing limits rather than being constrained by the CPU. The 94th percentile ranking among all CPUs and an average benchmark score of 69996 place this processor near the top of the performance spectrum, with nearest rivals including the AMD Ryzen 9 7940HX (0.2% higher score) and Intel Core i7-14700KF (0.2% lower score).

The Ryzen 7 9700F's 89.6 GB/s memory bandwidth via dual-channel DDR5 provides sufficient data throughput for streaming game assets. The PCIe Gen 5 interface with 24 CPU lanes ensures that the RTX 3070, which uses PCIe 4.0 x16, operates without interface limitations. The CPU's 80 KB L1 cache per core and 1 MB L2 cache per core contribute to low-latency access for frequently used data, supporting the high frame rates observed across all settings. At 4K Ultra, where the GPU is more heavily loaded, the CPU still delivers enough performance to maintain the 102 FPS average, indicating that this processor does not become a limiting factor in any tested configuration.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all settings. The Low preset achieves an average of 413 FPS, while Medium reaches 376 FPS with a minimum of 320 and maximum of 432 FPS. High settings produce 332 FPS average, and Ultra still maintains 270 FPS. These results indicate that at 1080p, the combination is capable of driving high-refresh-rate displays to their limits, with even the most demanding preset remaining well above 240 FPS.

At 2560x1440, performance remains strong but shows the expected reduction. Low settings deliver 276 FPS average, Medium achieves 251 FPS with a range of 213 to 289 FPS, High produces 222 FPS, and Ultra drops to 180 FPS. These figures suggest that 1440p is the sweet spot for this combination, offering high fidelity with frame rates that comfortably exceed 144 Hz even on Ultra settings. The Medium preset's minimum of 213 FPS ensures smooth gameplay without dips below typical high-refresh thresholds.

At 3840x2160, the system still performs admirably but with more variation across settings. Low settings deliver 156 FPS average, Medium achieves 142 FPS with a minimum of 121 and maximum of 163 FPS, High produces 125 FPS, and Ultra drops to 102 FPS. The 4K results remain playable across all presets, with Ultra still exceeding 100 FPS, though the gap between Low and Ultra narrows to 54 FPS compared to 143 FPS at 1080p. This compression suggests that at 4K, the GPU becomes the primary constraint, and additional settings overhead has less impact on overall performance.

The Medium preset at each resolution provides the most complete data with both minimum and maximum FPS values. At 1080p, the 320-432 FPS range shows a 112 FPS spread, while at 1440p the 213-289 FPS range spans 76 FPS, and at 4K the 121-163 FPS range covers 42 FPS. This narrowing spread at higher resolutions indicates more consistent frame pacing as the GPU becomes more uniformly loaded, reducing the impact of scene complexity variations.
